Instruction Of The Components Of The Bottle-Top Dispenser
The bottle-top dispenser is suitable for general acids and bases and low concentrations of strong acids and bases and salts.
It can be fine-tuned quantitative, fine-tuning for the physicochemical characteristics of different solvents; the reflux function of the three-function valve can avoid the waste of the solution, and is the standard configuration; the unique wiper seal ring effectively reduces the expansion and crystallization of the piston.

Suitable for general acids and bases and low concentrations of strong acids and bases and salts, such as H3PO4, H2SO4, NaOH, KOH, etc. The whole is made of ETFE, FEP, PFA, PP materials with a maximum pressure of 500 mbar, and a maximum viscosity of 500 mm s, the maximum temperature resistance is 40 ℃, the maximum liquid density is 2.2g / cm3. The easy-to-read digital capacity displays unique “simple calibration” technology allows you to complete the calibration work in accordance with ISO9000 and GLP standards in a few seconds +/- button to calibrate the adjustment knob, in accordance with ISO9000 and GLP standards, divided into three types, digital adjustable type, fixed type, and cursor type.

Almighty / hydrofluoric acid bottle dispenser
It is suitable for hydrofluoric acid, strong acid, fuming acid, alkali, solvent, and extremely dangerous liquid. It adopts an integrated PTFE structure. The material contacting with PTFE and sapphire during the liquid separation process. Strengthen the safety valve of safety protection to avoid the leakage of niacin / odorous chemical liquid odor. The dispensing cylinder conforms to the ISO 8655 calibration standard.
1-3 bottle-top dispenser: suitable for biological laboratory, biological use.
No. 4-8 bottle-top dispenser: suitable for chemical, chemical, trace analysis, and harsh environments.
Clean all the instruments of bottle- top dispenser, and connect the rubber pipe of the water outlet pipe and the glass pipe of the water outlet to the bottle cap. Curved glass tube
Put the end of the tube into a plastic suction nozzle, and then add the test solution to the storage bottle. Use the screw to tighten the storage bottle and the liquid dispenser, suck up and down several times, and discharge the bubbles in the bottle to apply. When using, first add the liquid according to the need, move the positioning sleeve to the scale mark on the positioning stem to fix it. It can be added continuously. If you need more precision during use, you can use the 111 models on the one hand, and after the calibration of the volume, on the other hand, you can fix the positioning sleeve correctly.
Type 111: align the upper convex part of the positioning sleeve with the center of the two rows of teeth of the positioning stem, then move up to the scale position of the required amount of liquid, and then turn left or right to insert the teeth on the positioning sleeve into the positioning stem In the tooth groove on the top, you can position it by tightening the positioning screw slightly.
When the test solution in the reservoir bottle is used up, do not unscrew the cap. You can pull off the water inlet cap, install a funnel and pour the required test solution into the bottle, then close the lid, and at the same time align the small hole on the lid with the gap of the water inlet to allow the gas to flow back. Rotate the cover until the small hole is closed to prevent the liquid from volatilizing.
Hawach can provide different types of the bottle-top dispenser to apply to every field. If you want to know more about it. Please contact us.
